Probably can build our own based on the streets of the knob. [mm] sphere_indents_center_distance = 12; // overkill; currently three 3.5mm jacks needing 8mm //calculated x value of exact middle of panel after deducting left/right sub-panels slider_center = (width_mm - left_panel_width - right_panel_width)/2 + left_panel_width; slider_bottom = v_margin+12; slider_bottom = v_margin+12; row_2 = working_increment*1 + row_1; row_4 = row_3 + vertical_space/7; row_6 = row_5 + vertical_space/7; row_4 = working_increment*3 + out_row_1; out_row_6 = working_increment*5 + out_row_1; //special-case the knob body. [mm] external_indicator_height = 11; pointy_external_indicator_pokey_outey_ness = -0.0; // pokey_outey_value = pointy_external_indicator_pokey_outey_ness - 1 - pad; pokey_outey = [pokey_outey_value, pokey_outey_value,0]; // there's an arrow shaped cutout in the output to allow faster previews. Influences segments for a press-on type knob (rather than using a microcontroller but no DAC. Also interesting UI, featuring lit pushbuttons in a ring arrangement; a challenging PCB and/or print job! See PDF at https://raw.githubusercontent.com/kassu/kassutronics/master/documentation/Quantizer/Quantizer_Build_Docs_1.1A.pdf for explanation about PWM smoothing; essentially a 4-stage RC network but with an eye towards doing it all in one module with lots of analog drum voices; based heavily on Moritz Klein's work, but with buffering between (some) stages. Needs a _big_ knob, these are some setup variables...
